Welcome to mex -setup. This utility will help you set up a default compiler. For a list of supported compilers, see http://www.mathworks.com/support/compilers/R2012b/win64.html

Please choose your compiler for building MEX-files:

Would you like mex to locate installed compilers [y]/n? y

No supported SDK or compiler was found on this computer. For a list of supported compilers, see http://www.mathworks.com/support/compilers/R2012b/win64.html

Answer 1

Which of the compilers listed at that link have you installed ? mex -setup will not download and install the compiler for you: mex -setup is for selecting which compiler you want to use once you have installed one or more compilers.
